5.6.2.a Ramp 2 (user-optional ramp)
This ramp is selected by closing the input for Ramp 2, TB1 –
terminals 5 & 6 (see section 4.2.5). If this input is left open, the TE
Series will respond only to Ramp 1 settings as listed above. Since
ramp 2 is always used as an alternate to the default Ramp 1,
different combinations of ramp profiles can be selected in F010.
Refer to Appendix 1 for additional information on ramp profiles.
F015 = Initial Torque (Voltage) of Ramp 2
Factory Setting = 60%
Range = 0 - 100%
Sets the initial voltage of Ramp 2 when F010 = 1 or 4. The initial
torque level should be set to provide just enough torque to make
the motor shaft begin to rotate while preventing torque shock
damage to mechanical components.
F016 = Initial Torque (Current) of Ramp 2
Factory Setting = 200%
Range = 0 - 600%
Sets the initial current of Ramp 2 when F010 = 2 or 3. The initial
torque level should be set to provide just enough torque to make
the motor shaft begin to rotate while preventing torque shock
damage to mechanical components.
F017 = Accel Ramp Time of Ramp 2
Factory Setting = 10 seconds
Range = 1 - 120 seconds
Sets the time between the initial torque set with F015 or F016
and either the Max Current Limit set with F018 or full output
voltage. Set the time to enable soft starts without stalls. Also
consider the motor's application. For example, centrifugal pumps
may require a shorter time. See notes for F013 for more details.
F018 = Max Current Limit of Ramp 2
Factory Setting = 350%
Range = 200 - 600%
Sets the maximum motor current that the TE Series starter will
allow during ramp 2. (This limit applies to both voltage and
current-type ramping.) The current will be limited to this setting
until either the motor reaches full speed or the over load
protection feature trips (F003).

Note:
Ramp 2 is often useful as a "bump start" or as a temporary Across-
the-Line start mode. Consult Appendix 1 for details.
